Health Minister Rona Ambrose says the case, which was located in Alberta, was an isolated one and that the risk to the general public is small.

‚ÄúThis case is not part of the seasonal flu, which circulates in Canada every year.‚ÄĚ

The H5N1 strain is unrelated to the seasonal flu outbreak, Ambrose added.

Health officials say the victim had travelled to China last month and was hospitalized after returning to Alberta on Jan. 1, then died two days later.

They say that while it remains unclear how the person contracted the virus, there is no evidence of human-to-human transmission.

‚ÄúThe health system did everything it could for this individual, and our thoughts are with the family at this time,‚ÄĚ Ambrose said.

Dr. James Talbot, Alberta‚Äôs chief medical officer of health, said that family members of the victim are being monitored and treated with medication, nothing that there‚Äôs nothing to indicate they are sick.

‚ÄúPublic health has followed up with all close contacts of this individual and offered Tamiflu as a precaution,‚ÄĚ Talbot said.

‚ÄúNone of them have symptoms and the risk of developing symptoms is extremely low. Precautions for health care staff were also taken as part of this individual‚Äôs hospital treatment.‚ÄĚ
